## Analysis

THE ACFT TOUCHED DOWN HARD ON THE GRASSY AREA 5 TO 10 FT SHORT OF THE RWY. THE PLT STATED AT THE TIME THAT HE FELT AND HEARD THE HYDRAULIC LINE BURST IN THE CABIN WHICH LEFT THE AIRCRAFT WITHOUT BRAKES. THE ACFT FAILED TO STOP AND CONTINUED TO ROLL OFF THE END OF THE RUNWAY INTO SHRUBS, TREES, AND UP AN EMBANKMENT WHERE IT CAME TO REST WITH THE NOSE GEAR FOLDED BACK. POST-CRASH EXAM REVEALED THAT THE HYDRAULIC LINE TO THE MAIN ACCUMULATOR HAD COME APART.
